html with io [May. 13th, 2008|07:50 pm]
[Tags|, ]

As promised, here is the code of my Io-based HTML DSL. The syntax looks like this:
html(
  head(title("ryan's web page")) 
  body(
    h1("sign my guest book!")
    form(action="/guestbook",
      p(
        label(for="name", "name")
        input(name="name", type="text")
      )
      p(
        label(for="msg", "msg")
        textarea(name="msg", "")
      )
      input(type="submit",value="sign")
    )
    h2("here is a list of numbers!")
    ul( 5 repeat(j,
      li("item number #{j}" interpolate)
    ))
  )
)
Does anyone care? Probably not :)

markaby-like html generation in io [May. 11th, 2008|06:17 pm]
[Tags|, ]

i'm working on a little DSL for making HTML using Io. Here's what it looks like
html(
  head(
    title("ryan's web page")
  ) 
  body(
    h1("ryan!")
    br
    form(action="/guestbook",
      h2("sign my guest book!")
      p(
        label(for="name","name")
        input(type="text",name="name")
      )
      p(
        label(for="msg","msg")
        input(type="text",name="msg")
      )
      input(type="submit",value="sign")
    )
  )
)
Currently functional at 80 lines of code. For this I intercept each function call before it does anything, walk through it's argument list and see if it's a single = expression. These are stored as attributes. The last argument of the function is evaluated and added as children. Here is what it looks like

libeio [May. 11th, 2008|01:59 pm]
Marc Lehmann, the author of libev, started development on libeio, a C language async io library. It's "similar to both the POSIX functions (just with a continuation/callback) and libev". Uses threads internally. Requests have two options for completion notification: they return an object that can be polled against or they take a callback. It isn't dependent on libev (or any event loop) but integration is easy. Read more about the design here.
